problems with Timers (by Ilie)
Timers of software do not correspond with reality , on output I have a led and watched the clock.
Pin soft time Realy Time 33 6 sec 1.35 min (95 sec) 34 50x60=3000ms(3sec) 1min(60sec) I do not understand why, in reality (physical) on electronic board are differences over the software program ? Thanks

I hope to understand Pin______________soft time____________ Realy Time 33_______________ 6 sec ________________1.35 min (95 sec) 34______________ 50x60=3000ms(3sec)____ 1min(60sec)

My guess would be that the processor is not running with the clock frequency that you specified to LDmicro.
In particular, note that it's running around 6/95 ~ 1/16 as fast as you expected. You specified a clock frequency of 16 MHz, so that corresponds to an actual clock frequency of 1 MHz. This is exactly what would happen if you neglected to program the fuses, since the ATmega32 runs off a 1 MHz RC oscillator by default. Check CKSEL, and the rest of the configuration bits.

Thank you veri much Jonathan . And hopefully return with result. I check .

Please tell me where should I check CKSEL in setings AVRdude or ... I use it to write. Thank you

Thanks so much for kindness, I do with avrstudio with picture settings and push progam. It work for that long time, but I did, the settings are on the external quartz 16mhz. Thank you veri much.
